In addition, regulations require that an emergency exit be installed in the ceiling of an elevator.

In conventional elevators, in order to inspect and replace lighting equipment, work was done through an inspection opening with a lid in the suspended ceiling. However, it was extremely difficult to work on lighting fixtures that were located far away. Therefore, for example, we responded as follows.

First, the conventional technology will be explained based on FIGS. 5 and 6.

FIG. 5 is a longitudinal cross-sectional view showing a conventional elevator car whole lighting system, and FIG. 6 is a cross-sectional view taken along the cutting line ■--■ in FIG.

) to form a double ceiling, the bottom surface (2a) is made of a translucent plastic plate to soften the illumination light, and the bottom surface is designed with a cylindrical hanging block (
2b) is attached integrally. (2C) is the hanging sky (
2) is located at the back corner of the bottom surface (2a) when viewed from the entrance/exit of the car room, and has a suspended ceiling inspection door (2d) that opens and closes downward; wall, (4) is the floor, (
5) is the door of the car room, and (6) is a lighting fixture disposed on the underside of the canopy (1).

In addition, (16) is a car frame top beam provided at the top of the car,
(17) is a rope shackle, (18) is a door machine,
(19) is a place, and (20) is a door closing technique.

Inspection and replacement work for the lighting fixture (6) of the conventional elevator car lighting system configured as described above is carried out through the inspection opening (1d) for the lighting fixture (6) on the entrance side, and the lighting fixture (6) on the back side ( 6) is carried out from the hanging ceiling entrance (2C) or the rescue exit (1a).

Next, another conventional technique will be explained based on FIGS. 7 and 8.

FIG. 7 is a longitudinal cross-sectional view showing another conventional elevator car lighting device, and FIG. 8 is a cross-sectional view taken along the cutting line ---■ in FIG. 7.

In the figure, the same reference numerals as in FIGS. 5 and 6 indicate the same or corresponding parts, so redundant explanation will be omitted here.

The difference between this conventional technology and the previous conventional technology is that the lighting equipment (
In place of the inspection port (1d) provided to improve the inspection and replacement workability of item 6), a suspended ceiling inspection port (2e) having an inspection door (2f) that opens downward on the entrance/exit side of the suspended ceiling (2) is provided. ).

Regarding this conventional technology, in addition to the hanging ceiling inspection opening (2), a hanging ceiling inspection opening (2e) is also provided on the entrance/exit side, so that the lighting on the entrance/exit side that is far from the hanging ceiling inspection opening (2c) is provided. Inspection and replacement of the appliance (6) can also be easily performed.

[Problem to be solved by the invention] However, the former conventional elevator car lighting device has the following problems:
Since the inspection port (1d) of the canopy (1) is placed on the car entrance side, in small elevators, the car frame upper beam (16
), Robe Shackle (17), Door Machine (18),
There is a place (19), a ventilation fan (not shown), etc.
Inspection may not be possible due to space constraints. Even in large elevators, you have to climb on top of the canopy (1) to work.
The work is time consuming and dangerous as the lighting equipment (6) may not be visible.

In the latter conventional elevator car lighting system, the hanging ceiling opening (1e) is located on the entrance/exit side, which is undesirable in terms of design, and therefore is often not approved by the customer.
